Trigger threshold
The adjustable trigger threshold determines the
volume the patient must inhale in order to trigger a
mechanical breath. The settings from 1 to 10
correspond to a trigger threshold of approx. 0.02 to
3mL.
Begin with a low trigger threshold. This
corresponds to a high trigger sensitivity. If auto-
triggering occurs, increase the trigger threshold.
An increased trigger threshold delays the
mechanical breath.
The display Trigger lights up briefly with each
mechanical breath triggered.
Setting the trigger threshold
1 Press the Vent. Option key.
The trigger threshold currently set (Trigger) is
displayed.
2 Reduce the trigger threshold by pressing the
key.
3 Increase the trigger threshold by pressing the
key.
Ventilation with pressure plateau
The patient can be ventilated with or without a
pressure plateau in the IPPV/IMV, SIPPV, and
SIMV ventilation modes.
In the PSV ventilation mode and when using the
additional setting VG, the pressure plateau must
always be set.
If a pressure plateau is set, inspiratory pressure is
limited to Pinsp.
Limiting the pressure to Pinsp prevents damaging
pressures, e.g., if compliance decreases. The
pressure plateau benefits the diffusion of the
breathing gas in the lungs.
1 Adjust the view so that the pressure waveform
and the measured pressure values are
displayed, see page 87.
2 Adjust ventilation using the following setting
knobs: Pinsp, PEEP/CPAP, T
I, TE,
3 Adjust the view so that the flow waveform and
the measured volume values are displayed,
see page 87.
4 Adjust the tidal volume using the following
setting knobs: Pinsp, PEEP/CPAP
5 Set the alarm limits, see page 84.
CAUTION
Risk of patient injury
High trigger sensitivity may lead to auto-
triggering of the ventilator.
Set the trigger threshold accordingly.
